guys sick of sify im finally planning to get dataone

guys sick of sify im finally planning to get dataone.. however i have read some conflicting opinions from dataone users.. there is this group who is really pleased with it and then still another thats had some bad experience.. i understand that this is the case with almost every isp but could someone please clarify these two issues :

1) the uptime - the reason that i am shifting to dataone from sify is bec of frequent downtime.. now the connection not working at the promised speed that i can handle.. downtime i cannot.. ive just faced three days of downtime and reached my limit... :angry:

2) there have been some issues abt inflated bills recieved by various users.. have any of you faced that problem? is the dataone system for counting the download data used accurate and reliable? cause i really dont look forward to recieving an inflated bill.. say wat u want abt sify bt atleast its prepay.. dont know abt u guys but reduction of a day in validity sounds better than having to pay hardearned $ lol

and thirdly which modem would u guys recommend.. i need one that would work reliably with linux.. thanks in advance :rolleyes:
